Phosphorus reacts with oxygen to form diphosphorus pentoxide: 4 P(s) + 5 O 2(g) -> 2 P 2O 5(s) If 0.97 moles of phosphorus ar
KengaRu [80]

Answer:

0.425 moles of P₂O₅.

Explanation:

As per given balanced equation, four moles of phosphorus reacts with five moles of oxygen to give two moles of P₂O₅.

As given that the initial moles of phosphorus taken = 0.97 moles

moles of phosphorus left after reaction = 0.12 moles

moles of phosphorus reacted = 0.97-0.12 = 0.85 moles

When four moles of P reacts they give two moles of P₂O₅.

when one mole of P will react to give = \frac{2}{4}molP_{2}O_{5}

0.85 moles of P will react to give = \frac{2X0.85}{4}= 0.425molP₂O₅

What is the strongest type of intermolecular force between solute and solvent in each solution?
vfiekz [6]

Dipole-Induced-Dipole is the strongest type of intermolecular force between solute and solvent.

<h3>What is Intermolecular Force ?</h3>

Intermolecular force is also called secondary force is the force of attraction between molecules. It acts between ions and atoms.

<h3>What is Dipole-Induced-Dipole attraction ?</h3>

A dipole-induced-dipole attraction is a weak attraction it occurs when the partial charge form with in the molecule due to uneven distribution of charge in a molecule.

CCl₄ is non polar in nature and CH₃OH is polar in nature so dipole-induced-dipole attraction is present.

Thus from the above conclusion we can say that Dipole-Induced-Dipole is the strongest type of intermolecular force between solute and solvent.
